虚拟机中CentOS的Nginx+keepalived 高可用集群配置教程

1.环境准备

首先两台虚拟机网络模式改为桥接
主机ip为192.168.96.254，
备用机ip为192.168.96.255，
VIP为192.168.96.250，
ps. IP地址根据自己实际情况修改

2.关闭selinux

关闭selinux
setenforce 0

编辑配置文件，关闭开机自启
vi /etc/selinux/config
将selinux=enforcing改成selinux=disabled

3. 为主机安装keepalived

下载
wget https://www.keepalived.org/software/keepalived-1.4.5.tar.gz

解压
tar -zxvf keepalived-1.4.5.tar.gz

进入文件夹
cd keepalived-1.4.5

预编译
./configure --prefix=/usr/local/keepalived

安装
make && make install

4.将keepalived注册为系统服务

cp keepalived/etc/init.d/keepalived /etc/init.d
cp keepalived/etc/sysconfig/keepalived /etc/sysconfig/
